Product De scription

Sure Klean Weather Seal Siloxane PD (predilute) is a ready to-use, water-based silane/siloxane water
repellent for concrete, GFRC, and most masonry and stucco surfaces. Siloxane PD is a low-V OC
treatment that penetrates more deeply than conventional water repellents and helps masonry resist
cracking, spalling, staining and other damage related to water int rusion. Low odor and alkaline stable,
Siloxane PD is ideal for field and in -plant application.

Application
Before applying, read “Protect” and “Precautionary Measures” sections in the Manufacturer’ s Product
Data Sheet for Weather Seal Siloxane P D. Refer to the P roduct Data Sheet for additional information
about application of Weather Seal Siloxane PD. Do not dilute or alter.

        Vertical Application Instructions
        1. For best results, apply protective treatment “wet-on-wet” to a visibly dry and absorbent
            surface.
        2. Alternate Application Methods

            Spray: Saturate from the bottom up, creating a 4” to 8” (15 to 20 cm) rundown below the
            spray contact point. Let the first application penetrate for 5 -10 minutes. Res aturate. Less will
            be needed for the second application.
Brush or roller: Saturate uniformly. Let protective treatment penetrate for 5 to 10 minutes.
Brush out heavy runs and drips that don’t penetrate.

Dense Surface Application Instructions
Apply in a single, saturating application with no run down. Back roll all runs and drips to
ensure uniform appearance. DO NOT OVER APPLY. One application is normally enough.
Always test.

Horizontal Application Instructions
1. Saturate in a single application. Use enough to keep the surface wet for 2 to 3 minut es
   before penetration.
2. Broom out puddles until they soak in. Treated surfaces dry to touch in 1 hour. Protect
   surfaces from rainfall for 6 hours following treatment. Many surfaces need several days to
   develop full water repellency.
